Abstract: A molded, non-metallic insert is disclosed that is of a form which replicates the seat configuration of the oxy-fuel cutting torch into which it is intended to be inserted. The insert material is compressible and resilient and allows a cutting tip, without special requirements, to be installed into the cutting torch so equipped with the insert. The insert is resistant to the difficult environmental conditions in which it is required to operate, in the industrial situations in which it is used. The insert resists elevated temperatures and the chemical and physical effects of the gases it contacts while sealing the flowpaths of the oxygen and fuel flowing through the torch head and cutting tip.
